another new guy

hello everyone, just got on the site and already have lots of questions what a surprise right? I have to install a new O2 sensor. My cobb tuner is telling me that its bank 1 sensor 2. Now the dumb queston, where do I start looking for it? any help would be great. Im a new subi owner so im not that confortalble just tearing into it and probably wrecking something. thanks!!!

when i was installing my front sway bar tonight I pretty sure i found it....I may be easier to take the front passenger wheel off so it i can get at it easier. I dont think it is under the intercooler. at least I hope not

See the above instructions that I copied from other sites.

You can see instructions in the first post for the 02-05WRX O2 sensor replacement... The location on the O2 sensor for the STi and the 06+ WRX is on the second post... And the third post is the rear O2 sensor. That one's cake. Start there. That's usually the one that's fouled, cut, damaged, modified, or removed anyways.

sorry for 4 posts... but I did not read your first post clearly. If this is new to you and you have a cobb accessport... please give me ALL of your modifications to your vehicle. The O2 code should be disabled with any map... but you have the accessport and an O2 code. So that makes me lean towards you having a previously modified car with a mismatched map! So please list ALL of your modifications! And look at the O2 sensor to see if it's removed, or let us know if you're catless... or if you have any modifications done to the O2 sensor (2.2kohm resistor mod, or the "anti-fouler" mod)
